Table 8 Predicted probabilities for panic disorder, agoraphobia and social phobia, and for any anxiety disorder respectively based on the prevalence and likelihood ratios associated with low (0–3), moderate (4–9) and high (10–24) 4DSQ anxiety scores

From: To what extent does the anxiety scale of the Four-Dimensional Symptom Questionnaire (4DSQ) detect specific types of anxiety disorder in primary care? A psychometric study
